Answer 2

Among the given options, HI has the highest dipole moment.

Explanation:

• Here, carbon dioxide has zero dipole moment because it is linear in shape and the two similar atoms on the sides cancels the dipole moment bringing the resultant moment zero.
• In case of water and sulphur dioxide the bent structure because of the lone pair present in then allows the two compound to have some dipole moment.
• Water will have greater dipole moment than sulphur dioxide as the two oxygen molecules repel each other more to come in a straight line that the two hydrogen molecules.
• In case of hydrogen iodide the two atoms are of great electronegativity difference and their is not similar hydrogen on other side to iodide ion to cancel its dipole nature.
